We Utter Kadosh Kadosh Kadosh to Negate the Klipos of Kini Kenizi and Kadmoni
Based on what we have discussed, we can add a fascinating tidbit. In his sefer Aderes Eliyahu (end of Balak), the Ben Ish Chai explains why we elevate ourselves from the ground each of the three times we utter the word “kadosh” in kedushah:
"כי על ידי שאנחנו אומרים שלש פעמים ק'דוש ק'דוש ק'דוש וקופצים מעל השלשה שבראש שהם ק'יני ק'ניזי ק'דמוני שגם הארץ, על ידי זה יתבטלו אותם כן ראשי תיבות שלשתן הוא קו"ף, ואנחנו מרימים עצמנו מעל הארץ, לרמוז שהקב"ה ירים וינשא ויגדיל אותנו על הכל".
By uttering three times k’adosh, k’adosh, k’adosh and jumping off the ground, the three primary klipos—the K’ini, K’enizi, and K’admoni—are negated; both sets of three begin with the letter “kuf.” We elevate ourselves off the ground to allude to the fact that HKB”H will raise, elevate, and make us greater than everything (everyone).
Now, we learned from the Shela hakadosh and the Minchat Chinuch that the Melech HaMashiach must first conquer the Kini, Kenizi, and Kadmoni—to complete the conquest of the ten nations HKB”H promised to Avraham—and only afterwards conquer the rest of the world. The song of the heavenly malachim reflects this same process. First they say: "קדוש קדוש קדוש ה' צבאות"—to subdue the klipos of the three nations whose names begin with the letter “kuf”— ק'יני ק'ניזי ק'דמוני –and then they go on to say: "מלוא כל הארץ כבודו"—that afterwards, when the Melech HaMashiach conquers the entire world, and it is imbued with the kedushah of Eretz Yisrael, the glory of His sovereignty will fill the entire world.
